The Evolutionary Genetics of Xiphophorus

Abstract

Fishes of the genus Xiphophorus, the platyfish and swordtails, are common inhabitants of the streams and rivers of Central America. The 15 species described occupy a variety of habitats, ranging widely through the Atlantic drainage from northeastern Mexico, south-east through Guatemala, Honduras and Belize. Like most other members of the family Poeciliidae, Xiphophorus species are internally fertilizing and ovoviviparous (Rosen and Bailey, 1963). Females can store sperm and produce broods for several months after a successful mating.
